I am having problems with my TV signal only when I turn it on for the first time. Blinks on and off, eventually gives me the blue screen with HDMI error/H1005. I have talked to tech support many times and have a new box with same issue. If I unplug the box and reboot it I finally get a picture. Everything is hooked up through my Yamaha receiver. I have changed HDMI cables out of TV and out of box to receiver. ATT support thinks their equipment is fine. Seems to me if unplugging it makes it reboot and work fine it is their problem. Any suggestions??

Just because restarting the U-verse box causes it to correct the issue does not necessarily mean that the underlying issue isn't the cable. The cable could be marginal and causing errors in the signal, enough errors that the U-verse box no longer sees the proper handshakes from the TV during a session. Or, it could be an issue with the U-verse box. Or it could be a combination of both.

You can purchase unlimited capacity for $30/month, which is less than most of the U-verse TV plans.
AT&T didn't invent HDCP. The studios caused it to be created and their contracts with AT&T (et al) require its use; it's also in BluRay players and any other consumer device that has an HDMI output. The software implementation in the AT&T box may be faulty, or it may be the implementation in your TV is faulty. If you've replaced 12 cables meeting the required standard, then I'd have to agree it's not just the cable.
Yes, using component bypasses the problem because component doesn't have HDCP built into it like HDMI does. And subjective video quality may be higher or lower with component than HDMI depending on your usage and eyeballs.

The $30 /month is to make whatever bandwidth plan you subscribe to have unlimited usage (similar to what have U-verse TV provides). You still have the basic bandwidth fee (which you'd have anyway, with TV if you also have Internet). There is often a multi-service "package" discount on Internet if you also have U-verse TV, so... if you had $50 Internet and $100 U-verse TV, you'd probably be paying $130 ($100+$50 - $20 multi-service discount), plus taxes and fees. If you dropped TV and added the $30 unlimited in place of the $100 U-verse TV, then you'd probably be paying $80 ($50 + $30). Still a $50 savings.
(Note; Other than the $30 monthly fee for unlimited usage, I'm really just making numbers up in this example).

For you it's likely your receiver. Sounds like you are going directly from receiver to TV...my situation was different as I was pushing everything through a HDMI splitter. Replacing the splitter worked for me.

We have the same problem and have switched out 3 HDMI cables and none of them worked. Your solution is a "workaround". The ATT box HDMI output worked fine with my older TV, but not with my new firetv. We know it is not the TV because HDMI from the TV works with several other devices. So you are just saying we are out of luck if we want to use the HDMI output on the ATT box. It is not a satisfactory work around.
